In slightly misguided effort to steer towards boating content, I have formed another oddball boat question or two...again. The generally accepted design for hulls seems to be a composite structure of resin and fiber, reinforced with wood. There is the guy who showed up with the aluminum deck boat with twin Evinrudes, but to my knowledge that is a one off deal. There are also "Snake River" style aluminum setups, and of course duck boats. Why isn't the use of alloys a popular choice among performance manufacturers? With the advent of the modern cad programs, panels could be cut, placed in jigs and welded. The flooring itself could even be made of the same material used for floors in commercial aircraft. I would think if structured properly, you could maintain, or even gain rigidity while shaving weight. It may be a point of diminishing returns as hulls get larger, but I don't know. Comments, knowledge and standard derogatory statements? Why's and why not's?
